My invention relates to hinges, and has particular reference to concealedor parti concealed hinges which are particularly we adapted for use in connection vwith automobiles, to connect the doors with the bodies thereof, whereby upon the opening of the doors, the sagging of the same is prevented.

An 'im ortant object of this invention is to provi e hinges of the yabove mentioned character, which are adapted to be cons nectcd with the door of an automobile yand so constructed that the door (the body of the automobile adjacent the door opening being laterally or vertically inclined and serving as a door jamh whereby the same is connected with the hinges) will have its upper end horizontally arranged when swung to the open position.

A further object of this invention is to provide a hinge ci the above mentioned character, which is simple in construction, cheap to manufacture, strong and durable.

Other objects and advantages of this invention .will-be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in' which like numerals are employed to designate like parts throughout the same, Figure 1 is an inner side view of the hinges, showing the saine in use, Fig. 2 is an outer side view of one-hinge, Fig. 3 is an edge view of the door and hinges with the door in its open position, Fig. 4 is a horizontal sectional view taken on line 4 4 of Fig. 1, F ig. 5 is a detailed section taken on line .5*5 of Fig. 4, and, Fig. 6 is a similar View taken on line 6-5 of Fig. l.

In the drawings, wherein for the purpose ofillustration is shown a preferred embodinient of my invention, the numeral 7 designates the side or body of an automobile and the numeral 8 designates an outwardly swinr ing door. The body/ 71 has its portion adyacent the door opening serving as a door jainb. The hody 7 and the door jarnh 9 are inclined from the vertical, as clearly shown in Fig. -3.- Particular attention is l; r Y.

called to the itact'that the door ja'no 9 is inclined the vertical, while in some aotoniotile bodies thefnoor jambe are verticaly arranged, which is ohtainahle fhy hai/'indr the side wall of the hotly foreed'or enge emitan. ny as employment or my hinges it is unnecessary to have the door jamo vertically arranged; which Ahas neen found to add considerably to the cost of the manufacture or" the automobile body.

he door jahh 9 is provided with upper 'and lower openings 1o for receiving the enter 11, which are lJ-shaped and have their inner sides open and their outer sides closed hy means of plates l1, as shown. These @shaped casings are provided at their ends with' outwardly extending flanges 12, which are rigidly connected with the door jamb 9 hy means of screws 13 or the like, as more clearly shown in Fig. 3. Adapted for insertion within the outer casings 10 are inner casings la, comprising si e strips 15. Thefinn'er ends of the side Patented Sent. 9, 1913.

strips i5 in each casing 1e are rigidly con- 80 nested 'by a stationary pin Vlo, provided with a conical portion 17 increasing in diameter downwardlyr and arranged eccentrica-ily with relation to the ends of the' pin 16, as 'more clearly shown in Fig. 6. The conical portion 17 extends transversely of the strips 15 toward their outer longitudinal edges. The side strips 15 are provided at their outer ends with outwardly extending anges 18, fitting within sockets 19 formed in the flanges 12. The flanges 18 are held in place by screws 20 or the like. .lt is 'thus seen that each inner Casing? le: may be removed from the casing 10 withont di'sturhingthe latter. y

Each hinge further comprises a U shaped arm 2l, one end of which is countersunk into the edge of the door and rigidly connected therewith by means of screws 22 or the like. Y shaped arm 21 Iis provided with an enlarged head 23, having a conical opening 241 formed therethrough for receiving the conical portion 17 of the pin 16. The upper and ldwer hinges are identical, except that the lower hinge is made suitably larger, the pin 16 of the lower hinge being arranged a greater distance from the adjacent edge of the door 8 than the pin 16 of the upper hinge.

Asclearly shown in Fig. Z, the U-shaped arms 21 and associated elements are coinpletely concealed from exterior view when The opposite end of the U- the door 8 is closed. When the door 8 is closed, the head .23 carried by the arin 21 is inclined from the vertical to have its longitudinal axis parallel with the longitudinal axis of the door janib 9which is trans versely inclined from the vertical, but, as shown in Fig. 3, when the door is moved to its open position, the head 9.3 is swung in a vertical plane transversely o'l the longitudinal axis of the door janib l), whereby its longitudinal axis will be vertically arranged and disposed at an angle to the longitudinal axis of the door janib S). ln this manner the head 23 and arm 21 carried thereby, are swung,r in a vertical plane transversely ot' the body 7, to maintain the door horizontal when moved to its open position.

'It is to be understood tlial the l'orni of my, invention herewith shown and described, is to be taken as a preferred example of the saine, and that certain changes in the shape, size and arrangement of parts may be resorted to witliont departing from the s irit of the ini'ention or the scope of the su joined claims.

Having described iny invention, l

' claim 1. In a hinge of the character described, the Combination with a casing,r to be nionnted upon a door janib which is inclined trom the vertical, of an arm to be connected with a door, means pivotally connect-ing the arm with the casing and adapted to automatically swin the arm upwardly while the same is being swung horizontally toward its open position, and means concealing the several parts of the hinge 't'roin an exterior view.

2. In a hinge of the' character described, the combination with a casing to be mounted upon a door jrainb which is inclined from the vertical, of an arin to he connected with ,A a horizontally swingingr door, and means standing axis of the door jamb when the door is closed and its upstaadirg axis iiiclined from the vertical and arranged at an angle to the npstanding axis of the. door jamb when the door is moved to the open position. i

3. ln a hinge of the character described, the crnnhination with a casing;r having one side closed and its op iosite side open, of a pin mounted williin the casing and rigidly con'nected therewith and having; its longitudinal axis parallel with the upstanding axis ol the casing, said pin being' provided with a conical portion which increases in diameter downwardly and is eccentrically arranged with relation to the longitudinal axis ot' the pin` and an approximately U- shaped arni to be attached to a door and carrying a head having a conical opening lo receive the conical portion of the pin.

4. ln a hinge ol the character described` ,the combination willi a pin provided with a conical portion which is ecceiilrically a1'- rang'ed with relation to the longitudinal axis ol the pin, meansrigidly connecting the pin willi a door jamb ot' an automobile body so that the longitudinal axis; at the pin is parallel with the longitudinal axis of the door jamb and the conical portion of said pin extends outwardly and trans` versely ot thc door jamb, and an arn'i to be connected with a door and carrying a head provided with a conical opening for re ceiving the conical portion of the pin.

[n testimony whereof I atlix my signature in presence ot' two witnesses.
